If you're a musician who likes to learn new songs and techniques by listening to the same piece of music over and over but wish that the music could be played a little slower, then you'll enjoy Amazing Slow Downer.

You can repeat any section of the music at full speed, slow it down or even speed it up by changing the speed between 25% (1/4 of original speed) and 200% (double speed) without changing the pitch!

Change the tuning or musical key? No problem, Amazing Slow Downer handles that as well.

Setup seamless loops by touching the "Set" buttons during playback.

Amazing Slow Downer is the ideal tool for any musician, transcriber or dancer wanting to improve their skills.

Supports playback of streaming "Apple Music" audio!

Note: Some functions such as "Pitch change" and "Equalizer" are not available when playing "Apple Music" songs.
"Apple Music" requires iOS 10.3 or better.

What’s New

Version 6.5.7

New - Support for more key commands when using a BlueTooth keyboard (or page turners)
Bug fix - "Apple Music" songs could possibly skip loops when "Change Speed at New Loop" was enabled

Expensive but better than free music slow-down apps

I tried several free apps before forking out for this one. The free apps had clunky user interfaces and lack the same precise control over speed that ASD has. Other functions such as simple looping were missing, and in one case an app didn't have a restart option so we had to wait for the piece to finish or at least speed it up to finish it.
This app is used by my kids' music school so I finally figured it was worth buying. They practice piano five days a week and the app is invaluable when they are mastering new pieces. Slowing it down so they can actually keep up boosts their confidence and before we know it, they are playing full speed (or faster as one of them likes a challenge).
Didn't rate it five stars as the UI could still be improved, such as importing more than one song at a time.

Brilliant App

This app has made a very positive impact on the way I practice and transcribe music. I also use in all my lessons as a guitar teacher. The way in which your Apple Music library is automatically loaded on and is so accessible is the main draw. The looping functions were a little clunky at first (I’d love a punch in and out button that let you set loop points as you play) but works well once you get used to it.

If the developer is reading this, thank you so much, this has made a huge contribution to my practice and I’m recommending to all my friends. I would recommend working a little on the presentation. This app could go viral if it had a more professional looking logo and a better name.

Good app

It’s a really good app but there is often few bugs the most annoying one is if I workout on a song and go away from it and come back to my phone it’s nearly impossible have to spend 10 min trying to reopen the song again but all other songs are opening fine it’s frustrating me and the playback does get stuck
